I agree. That means a LOT of codes will have to be ported from CUDA to 
whatever AMD uses. I know AMD announced their HIP interface to convert 
CUDA code into something that will run on AMD processors, but I don't 
know how well that works in theory. Frankly, I haven't heard anything 
about it since it was announced at SC a few years ago.

I would not be surprised if AMD pursued this bid quite agressively, 
possibly at a significant loss, for the opportunity to prove their GPUs 
can compete with NVIDIA and demonstrate that codes can be successfully 
converted from CUDA to something AMD GPUs can use to demonstrate GPU 
users don't need to be locked in to a single vendor. If so, this could 
be a costly gamble for the DOE and AMD, but if it pays off, I imagine it 
could change AMD's fortunes in HPC.
